1. Photosynthesis and Respiration
Cellular Energy
Photosynthesis and Respiration

2. Autotrophs--Photosynthesis
Takes light energy and converts into food
Reactants
Products

3. Photosynthesis Formula
6 CO
6 H2O
C6H12O6 +
6 O2 O2
CO2
Sugar
Green plants use the energy of sunlight to convert carbon dioxide and water into high-energy sugars and oxygen

4. HIGH NUMBER OF CHLOROPLASTS = PHOTOSYNTHETIC ORGANISM!!!
Water
CO2
Carbon Dioxide
HIGH NUMBER OF CHLOROPLASTS = PHOTOSYNTHETIC ORGANISM!!!
Light
dependent
Chloroplast
w/pigment
chlorophyll O2
C6H12O6
GLUCOSE

5. Chemical energy and ATP
ATP (Adeonsine Tri-Phosphate)
Is the principal component that cells use to store and release ENERGY when its broken down
Adenine
Ribose
3 Phosphate groups

6. Where does ATP come from???

7. Cellular Respiration
Cell respiration is the breaking down of glucose and other food molecules in order to release energy, in the form of ATP
Food
Energy

8. Respiration vs. Photosynthesis
Respiration is the reverse reaction of photosynthesis

9. Cell Respiration Formula
C6H12O6 +
6 O2
6 CO
6 H2O O2
CO2
Sugar

10. Two Types of Cellular Respiration Review
Anaerobic Respiration
Aerobic Respiration
Can only occur in the presence of oxygen
Produces water and carbon dioxide
Generates 36 ATP!!!
Occurs without the use of oxygen
Produces lactic acid or alcohol and carbon dioxide
Generates only 2 ATP
So….which one is more efficient???
